Many of the problems Jeeps and slow-moving rockcrawlers encounter on the trail are due to overheating. At slow speeds there simply isn't enough airflow through the engine compartment to keep things cool. Worse, engine compartments on most vehicles are poorly vented, with no way for hot air (which rises) to escape from the upper areas of the engine bay. Poison Spyder's Hood Louvers solve that problem by promoting proper airflow through and out of the engine compartment, while adding great looks to your Jeep.

NOTE: This item fits JK's with a single windshield washer nozzle, which should be 2007-2012 models (please physically check yours before ordering, as there may be some discrepency between this feature change and the model year change). A version designed to fit the 2013 & later models, with two windshield washer nozzles, is available HERE.

Cool That Engine!
The Poison Spyder Hood Louver helps keep your engine running cool by promoting airflow through the engine compartment. Many factors can contribute to high under-hood temperatures, which can translate to higher engine coolant temperatures and overheating. Headers, slow speeds, flex fans, and the cramped spaces of the engine compartment can all contribute to increased heat and reduced airflow. This Hood Louver kit frees up airflow through the engine compartment, allowing hot air to escape and cooler air to be drawn in through the radiator, improving cooling of both the engine coolant and under-hood air. Rock-crawlers and slow-moving vehicles are especially susceptible, as slower speeds naturally result in reduced airflow.

Great Looks
In addition to improved cooling performance, Poison Spyder Hood Louvers add great looks to your Jeep! The Poison Spyder Hood Louver looks great on any Jeep, whether it is painted to match the body color or powder coated a contrasting color. For convenience, it is available either bare or powder coated black. Adding to the great looks are the stainless steel button head cap screws used to fasten the louver to the hood.

Good Value For the Price
A Poison Spyder Hood Louver is one of the best bang-for-your-buck improvements you can do for your Jeep. Compare it to the cost of a complete replacement hood with vents, such as those from AEV, and its easy to see what a great value the Poison Spyder product is.

Easy Installation
Hood Louvers are fairly easy to install but do require some drilling and cutting of your hood. Stainless steel fasteners are supplied, as well as a full-size template with instructions for cutting the airflow holes in the hood. Because it is a one-piece design, specific for each model Jeep, installation is a quick and easy. Competitors' hood louver products may include multiple pieces that are painstaking to properly align and install, while others provide no cut template, leaving you to figure out how best to place the louver and cut the holes underneath.

Superior Packaging
We've put almost as much engineering into the packaging as we did for the louver itself! As a rather large, unwieldy piece, it is imperative that the Hood Louver be properly packaged to ensure against shipping damage. Our custom box and CAD designed foam blocking are your best insurance against the hassles of possible shipping damage.

IMPORTANT: Many of the installed photos in the gallery below show an earlier version of the Hood Louver, which featured the full Poison Spyder logo cut out at the top end. The current design features just the "Spyder" emblem by itself, without the Poison Spyder lettering. The logo was the only change.

At Poison Spyder we strive to build superior features into every aspect of each product we make. Every feature has a reason for being included in the design. Here are a list of the most important of these features, along with an explanation of the benefits of each. Consider these important factors when shopping for products, and compare the competition to Poison Spyder's features and benefits!

Feature

Benefit

Louvers

Allow hot air to escape the engine compartment, keeping under-hood temperatures cooler. Improved airflow out of the engine bay also helps improve airflow into the engine bay, including through the radiator, helping your radiator and fan operate more efficiently.

One-Piece Construction

Easier to install than kits that consist of several separate pieces. Helps add rigidity to the flimsy stock sheetmetal of the hood, helping to reduce "hood wobble".

Heavy Gauge Aluminum

Lightweight and corrosion resistant. Helps add rigidity to the flimsy stock sheetmetal of the hood, helping to reduce "hood wobble".

Separate Hardware

Some competing products use a pressed-in threaded stud rather than the through-bolt hardware we use. The metal studs can be easily damaged in shipping, are prone to dislodging, and can be very difficult to lign up with bolt holes that may be slightly off due to drill wander. They are also made of normal steel rather than the great looking, corrosion resistant stainless steel fasteners we use.

Superior Packaging

Poison Spyder's engineered, well-thought-out packaging for the Hood Louver ensures the product will arrive undamaged, with less chance of the hassle of filing shipping damage claims.

Q: Does the Hood Louver allow water to get into my engine compartment?

A: This is a very common question that we get asked all the time. The simple answer is yes, some water can trickle down through the louvers during wet weather, but this hasn't caused any significant problems for the hundreds of people who have installed our Hood Louvers. It is important to remember that the engine bay is not a sealed compartment—it is common and expected that water can splash up into there even with a stock, uncut hood. That's why all of the engine components and electrical connections under the hood are weatherproofed from the factory. Many Jeep owners routinely pop the hood and hose down the engine compartment anyhow, to clean off dust and mud after wheeling trips, with no ill effects. Even if you live in an area with wet weather, you can install the Poison Spyder Hood Louver with confidence.

Q: I keep stripping the small screws, what am I doing wrong?

A: Our Hood Louvers are installed using small, stainless steel button head cap screws. We've heard a few complaints from customers who have stripped out either the threads or the internal hex socket on these. Here are a few thoughts to keep in mind when using them. First, the alloy used in stainless steel fasteners is not as hard as a Grade 8 bolt, so more care must be taken when installing them. Always use anti-sieze compound on the threads, especially when installing products that require pre-installation, removal, then final installation, such as with the Hood Louver kit. The lock nuts used in these kits are zinc plated steel and of a harder alloy than the stainless steel cap screws, so the threads can gall more easily if they are cross-threaded or over-tightened. Also when using the hex key (Allen wrench), make sure the hex key is fully seated into the hext socket in the head of the screw, and not tilted at an angle. And ALWAYS use flat-ended hex keys with stainless steel fasters, never use ball-end hex keys with them. Also, try holding the head of the screw stationary with the hex key, while turning the nut with the wrench. This will make it easier to keep the tool straight and apply constant pressure while tightening. Finally, DO NOT OVER TIGHTEN.

I got a bare hood louver because I wanted to be able to customize my louver to match the rest of my vehicle and so I rhino lined it. The louver itself was a nice pressed sheet of quality metal which I really liked. The only downfall was the actual stencil itself didn't quite line up right but that was inevitable because I installed it on my 2006 Nissan Frontier. I said f^â‚¬% this and just lined the louver up as straight as possible and started punching wholes and it still came out badass. (Very little margin for error so measure 3-4 times then cut lol)

Completely love the look and performance of the hood louver! Fits the style I was looking for and added the airflow I needed with the supercharger I added a few months ago! Noticeable change in response when the engine is at temperature, since the charger added a lot of heat in the engine bay. Install took longer than I expected however I took my time considering I was cutting holes in a perfectly good hood, I would have never heard the end of it from the wife if I had to buy a new hood. Instructions were very clear and precise. Made all cuts with a cutoff wheel on my grinder and Dremel on the corners. Very impressed!

Looks freakin' great. Easy install and didn't take too much time. I would def encourage anyone who wants to dissipate more heat from your engine compartment and look aggressive, this is the way to go!!!!
